Counting Neighbours Sudoku
(Published on 31. May 2020, 18:45 by Carrick22)
Apply classic Sudoku rules : Each row, column and bold-outlined region must contain the digits 1-9 once.
Furthermore :
- A digit in a cell with a circle indicates the number of different digits in all 8 neighbouring cells (horizontal, vertical and diagonal).
- A digit in a cell with a cross indicates the number of different digits in all diagonal neighbouring cells.
- All possible circles and crosses are given, so the property doesn't hold for unmarked cells.
You can use Penpa-edit for solving it on your browser.
Solution code: Row 2, followed by column 8.

@olima: most simple method is just to ask in the forum if there is someone willing to test your creation.

Although this puzzle was tested, a problem in file sorting lead to me putting the wrong images. The red square is nothing to be worried, it was a fast screenshot and I didn't see that.

@Richard Gibt es einen speziellen "Spielplatz" für ungetestete Rätsel hier auf dem Portal?

My advice (to all authors in the portal): have your puzzle tested before publishing...

I am so sorry, this was the previous version of the puzzle. This is the polished version, with a unique solution.

Erster, wenn auch erst im zweiten Anlauf richtig gelöst - und ich meinen Fehler in der ersten Lösung noch nicht gefunden habe.
